Summary
The new bone conduction implant (BCI) 602 shows excellent audiological outcomes and minimal complications in adults and children with hearing loss. This systematic review confirms its safety and reliability for mixed or conductive hearing loss.
Area of Science:
- Otolaryngology
- Biomedical Engineering
- Audiology
Background:
- The bone conduction implant (BCI) 602 is a novel, smaller transcutaneous device.
- Limited studies exist due to small patient numbers, impacting statistical power.
- This review focuses on early outcomes for mixed or conductive hearing loss.
Purpose of the Study:
- To systematically review and meta-analyze audiological and medical outcomes of the BCI 602.
- To evaluate outcomes in both adult and pediatric patient cohorts.
- To assess the safety and efficacy of the BCI 602.
Main Methods:
- Systematic review and meta-analysis following PRISMA guidelines.
- Inclusion of 6 studies from 108 reviewed.
- Analysis of pre- and postoperative data using fixed-effect and random-effects models.
Main Results:
- 116 patients (64 adults, 52 pediatric) evaluated.
- No intraoperative adverse events; low postoperative complication rates (3.1% adult, 3.8% pediatric).
- Significant improvements in sound field thresholds (MD, -27.05 dB), SNR (MD, -6.35 dB), and word recognition (MD, 68.89%).
Conclusions:
- BCI 602 implantation demonstrates high safety and reliability.
- Excellent audiological outcomes observed in both pediatric and adult groups.
- Further research needed on long-term outcomes and direct comparisons with other BCIs.
